FLOMAG / Corosex Magnesium Oxide Media .66 cu. ft. , pH Correct Acidic Water, **Free Shipping**

FLOMAG / Corosex , Magnesium Oxide Media  By neutralizing the free carbon dioxide in water, Corosex can correct red water conditions and render it to a non-corrosive condition. Corosex, being a reactive magnesium oxide, is used most effectively where pH correction is substantial or high flow conditions are in use. Corosex being soluble to acidity, will have to be replenished periodically. Please note, under certain conditions, Corosex may over correct and create a basic / alkaline condition.Corosex may be effectively combined with Calcite to combine the  high flow neutralization properties of Corosex, along with the slowing reacting low flow properties of Calcite reducing potentially high alkaline properties due to over correction. Corosex must be blended with Calcite at a ratio of 90% Calcite and 10% Corosex, or 80% Calcite to 20% Corosex. Higher ratios can be used. Please contact us regarding that application. Many other factors must be considered in design. Free Shipping lower 48 st
